Membranes/Capsheets

StressPly® Max / Max FR Mineral

Maximum Strength
Exceptional Weathering
Superior Fire Resistance

StressPly Max membranes offer a robust solution for the toughest environments. Utilizing a dual polyester and fiberglass reinforcement, StressPly Max has superior tensile values supported by the graphene-enhanced modified bitumen. StressPly Max is formulated with Garland’s additive blend called TripleBoost, which provides superior mineral embedment and reduces thermal degradation of the finished membrane.

Product Specifications

Method	Description
Hot-Applied	StressPly Max membranes can be used with ASTM D 312, Type III or IV asphalt, Garland’s HPR All-Temp Asphalt or Garlastic KM Plus. Two plies of HPR Glasfelt, ASTM D 2178, Type IV or VI fiberglass felt or a Garland-approved modified base sheet are solidly bonded to the approved substrate. The StressPly Max membrane is then solidly bonded to these base layers with hot asphalt.
Cold-Applied	StressPly Max membranes can also be applied in Garland’s cold- applied Weatherking® or Green-Lock® Plus Membrane Adhesive. One or two layers of heavy-duty Garland-approved modified base sheets are applied in Weatherking or Green-Lock Plus Membrane Adhesive to the approved substrate. The StressPly Max membrane is then adhered to these base sheets with Weatherking or Green-Lock Plus Membrane Adhesive.
